Profile: Corbin was certainly the least-hyped of the prospect trio including himself, Trevor Bauer and Tyler Skaggs waiting in the wings for the Diamondbacks last season, but judging by 2012, he may have the best immediate returns. Corbin posted just a 4.54 ERA but a sharp 4.00 FIP despite serving up 1.18 home runs per nine innings. He can get grounders (45.7%) and he exhibited both sharp control and decent strikeout stuff. With a fastball that can touch the mid-90s and a changeup to neutralize lefties, Corbin will be a solid sleeper if he can win a job in the Diamondbacks' rotation this season. (Jack Moore)

The Quick Opinion: Corbin will have to beat Tyler Skaggs to win the fifth starter spot in Arizona. If he does, he'll be a solid sleeper for the 2013 season.

Profile: Corbin was easily one of the bigger surprises of 2013 as he was virtually undrafted in fantasy leagues and finished 27th among starters in Wins Above Replacement. The biggest reasons for the breakout were a slight change in his pitch mix and better luck on balls in play. As for the pitch mix, Corbin's slider was a much more effective pitch than his change up in 2012 according to our pitch values, and he increased the slider usage and decreased the change up usage in 2013. His slider also turned out to be one of the fifteen best sliders among starters last year. As for the luck on balls in play, a 34 point drop in batting average on balls in play never hurts. His BABIP was extremely low early in the year with a .247 first half BABIP, but it evened out somewhat with a .337 second half BABIP. His strand rate followed a similar path. As a result of the BABIP and strand rate leveling out, it looks like Corbin faded down the stretch with an ERA of around six. But his strikeout and walk rates remained similar, and his ERA remained under four in every month of the season. Ultimately, Corbin got a little more good luck than bad and should probably expect his roto numbers to rise a touch more in 2014. The Steamer projection seems on the money. Combined with above average strikeout and walk skills, Corbin should still be an above average starter next year. But maybe a top 40-50 starter as opposed to top 30. (Brett Talley)

The Quick Opinion: By altering his pitch mix a bit and getting better luck on balls in play, Corbin broke out in 2013. All of the better luck came early in the year, so the regression makes it look like he faded down the stretch. But his skills remained constant throughout the season. He may be in line for a touch more regression in 2014, but he should still be an above average starter and a top 40 starter in fantasy leagues.

Profile: Corbin had a good 2013 and hoped to build on it in 2014. His elbow didn't agree and he needed Tommy John surgery. Right now he is expected back in June. It will be interesting to see where his talent level stabilizes when he does return. His velocity saw a jump from 2012 to 2013, and along with it came a bump in strikeouts. Will he keep both the velocity and the strikeout rate up? Usually command is one of the last skills a pitcher gets back after Tommy John surgery, so could he see more walks? Right now he should be a late round draft pick and a DL stash at best. Don't make a call on him until a better picture of his health emerges, if possible. Actually throwing off the mound this spring would be a hopeful news item for his potential owners. (Jeff Zimmerman)

The Quick Opinion: Patrick Corbin is coming back from Tommy John surgery. His return date and talent level are both up in the air at this point.

Profile: Patrick Corbin successfully returned from Tommy John surgery in July of 2015 and turned in 16 very encouraging starts for the Diamondbacks. His average fastball velocity was actually a tick higher than his career average and he was stingier with the walks than he demonstrated in 2013 with just a 4.8% walk rate. FIP pegged him at 3.35 over his 85 innings pitched, which is right in line with the promising 3.43 FIP Corbin turned in over a full season in 2013. Just 26, Corbin isn't likely going to carry your fantasy squad strikeouts, ERA, or WHIP but he's a more than capable back end starter on a good staff, who has enough upside to make him a nice target later in your draft. (Michael Barr)

The Quick Opinion: It was full steam ahead post-Tommy John for Patrick Corbin, who didn't see that typical loss of control many other hurlers experience after their elbow gets the MacGyver treatment, and he even saw a little more zip on the fastball to boot. Target him as your fourth or fifth and hope you catch lightning in a bottle.
